Abstract – The combining of fibres, often called hybridization, is investigated in this paper for a M40 grade concrete. The addition of two or more types of fibres in concrete with suitable combination may increase overall properties of the concrete. In this research, concrete is made with addition of different proportions of hybrid (steel & polypropylene fibres). Steel fibres added with percentage of 0.5%, 0.6%, 0.7% & 0.8% by volume of concrete and polypropylene fibres added with percentage of 0.5%, 0.4%, 0.3% & 0.2% by weight of cement. Compressive strength, splitting tensile and flexural strength and acid test were performed and results were analyzed. The test results show when adding these proportions of fibres then the strength will gradually increases than control concrete.

Keywords— compressive strength, hybrid composites, split tensile strength & flexural strength , durability
